jQuery使用相同的数组查找和删除数组中的字符串

jQuery find and delete string in array using same array

本文关键字：数组 删除 字符串 查找 jQuery      更新时间：2023-09-26

我问了这个问题：Javascript/jQuery在数组的其余部分查找并删除数组值，但我觉得我解释错了。这是我的第二次尝试。

我正在使用PHP的imap函数提取电子邮件。我能够成功地提取电子邮件。下面是一个代码片段，展示如何对其进行编码。

foreach($all_email_dates as $email){
    $email_id = explode(":", $email);
    $email_id = $email_id[1];
    $email = imap_fetchbody($inbox, $email_id, 1.1, FT_UID);
    if($email == "") $email = imap_fetchbody($inbox, $email_id, 1, FT_UID);
    if(imap_base64($email)) $email = imap_base64($email);
    $email = quoted_printable_decode($email);
    $email = preg_replace('/(^'w.+:'n)?(^>.*('n|$))+/mi', '', $email);
    array_push($emails, $email);
    echo $email;
    echo "<:>";
}

这会提取我需要的所有电子邮件，并按时间顺序排列。

现在，我使用AJAX调用获取它们，并尝试在这里操作它们：

$.post('php/contacts-get-email.php', {email:email}, function(data) {
    var email_body = data.split("<:>"); //Puts each email into an array
    console.log(email_body);
    //I have test code here for now that is not working
});

我想做的是遍历该数组（email_body），并查找和删除任何重复的字符串。上面的输出如下所示：http://jsfiddle.net/exdjumqm/.（我把它放在小提琴里，而不是这里，因为它在这里显示太长了）---ADD这里还有一个JSON文件可以玩：http://412webdesigns.com/uploads/emails.json

主要目标是删除以前在电子邮件中的任何文本。如果可能的话，我想保留回车符用于格式化。

例如，第一封电子邮件有一段文本，显示在电子邮件2和4中。我希望删除那条短信。但我不确定从这里到哪里去。

如果你需要更多的细节，请告诉我。谢谢

更新以下是粘贴在此处的电子邮件字符串：

第一封电子邮件

Thanks so much name! We had a great time today too and can't wait to 
see'r'nwhat the pictures look like! Looking forward to seeing them when you're 
all'r'ndone editing! Thanks again :)'r'n

第二封电子邮件

Hi name!'r'n'r'n'r'n'r'nThank you for the email! You don't have to wait any 
further!'r'n'r'n'r'n'r'nWe were able to get around 70 pictures that we think 
were noteworthy! To  'r'ndownload ALL of your pictures, head to 
www.site.com'/download  'r'nand use the password '"AN5k9W'". This should 
automatically start your  'r'ndownload, so check your downloads folder. It's a 
half of a gig, so the file  'r'nis pretty large!'r'n'r'n'r'n'r'nTo check out 
some of the pics while you're waiting on the download, head to  
'r'nhttp:'/'/site.com'/#'/151108-name_name-engagement or  
'r'nfacebook.com'/site. Remember to like us and share your pics  'r'nwith 
anyone you want!'r'n'r'n'r'n'r'nLet us know what you think!'r'n'r'nWe look 
forward to henameng from you!'r'n'r'nname & name'r'n'r'n'r'n'r'nOn Sun, Nov 8,

您会注意到第二封电子邮件包含第一封电子邮件，因为它是对第一封电子邮件的回复。

var formatted_email_body = []; // Init a blank array
var email_body = data.split("<:>");
for(var i=0; i<email_body.length; i++)
{
   if(formatted_email_body.indexOf(email_body[i]) == -1) // If not in the new array
       formatted_email_body.push(email_body[i]); // Push it
}

现在formatted_email_body是一个只有唯一值的数组。

由于这个问题被淡化了，我只想给出一个目前对我有效的答案。。。

我回到了php，并使用了一些"规则"来减少电子邮件垃圾。如果有人感兴趣，以下是规则：

//Get your email
$email = imap_fetchbody($inbox, $email_id, 1.1, FT_UID); //check body types
if($email == "") $email = imap_fetchbody($inbox, $email_id, 1, FT_UID);// check body types
if(imap_base64($email)) $email = imap_base64($email);//decode base64 if it is
$email = quoted_printable_decode($email); //Decode the Email
$email = explode("'r'n'r'nOn", $email); //split the email if the reply starts with "On this day, this person wrote"
$email = explode("'r'n>", $email[0]); //Split the email again if the line starts with a line break and "less than" sign (>) which usually denotes a reply 
$email = str_replace("'r'n'r'n", '<br />', $email[0]); //Give normal line breaks to double carriage returns and newlines
$email = str_replace("'r", ' ', $email); //Give spaces to unused carriage returns
echo $email;

根据您的评论，我创建了一个函数uniqPages。希望你觉得它有用：）
